MVVM ObservableCollection<> ListView

目标：在ListView中，设两列，一列表示人的姓名，一列表示年龄，用ObservableCollection<>来实现。

编程：

1）定义类Person

public class ABC:INotifyPropertyChanged

{

#region INotifyPropertyChanged 成员

public event PropertyChangedEventHandler PropertyChanged;

public void RaisePropertyChanged(string PropertyName)

{

if (PropertyChanged!=null)

{

PropertyChanged(this, new PropertyChangedEventArgs(PropertyName));

}

}

#endregion

private string name;

public string Name

{

get { return name; }

set

{

if (name!=value)

{

name = value;

RaisePropertyChanged("IP");

}

}

}

private int age;

public int Age

{

get { return age; }

set

{

if (age != value)

{

age = value;

RaisePropertyChanged("Age");

}

}

}

public ABC() { }

public ABC(string ip,int age)         {             this.Name = ip;             this.Age = age;         }

2).按照MVVM的模式，设计一个ViewModel，在此类中定义ObservableCollection<>:

public Class PracticeViewModel

{

public ObservableCollection<ABC> collection = new ObservableCollection<ABC>();
        public void InitialCollection()
        {
            collection.Add(new ABC("Betty", 23));
            collection.Add(new ABC("Jully", 24));
            collection.Add(new ABC("Tom", 25));
        }
        public PracticeViewModel()
        {
            InitialCollection();
        }

}

3).定义数据上下文

PracticeViewModel vm = new PracticeViewModel();
            this.DataContext = vm.collection;

4).写xaml代码

<ListView ItemsSource="{Binding}">
            <ListView.View>
                <GridView>
                    <GridViewColumn Header="姓名"  DisplayMemberBinding="{Binding Name}"/>
                    <GridViewColumn Header="年龄"  DisplayMemberBinding="{Binding Age}"/>
                </GridView>
            </ListView.View>
</ListView>

现在的问题是：还没搞清楚listView的ItemSource里面应该Binding 什么，虽然老师讲了，当时感觉明白了，结果试了试发现还是有问题，继续学习。
